Vijayadashami is observed for different reasons and celebrated differently in various parts of the Indian subcontinent.In the southern, eastern, northeastern, and some northern states of India, Vijayadashami marks the end of Durga Puja, commemorating goddess Durga's victory against the buffalo-demon Mahishasura to restore and protect dharma.In the northern, central, and western states, it marks the end of Ramlila and commemorates the deity Rama's victory over the demon-king Ravana.Alternatively, it marks a reverence for one of the aspects of goddess Devi, such as Durga or Saraswati.
Vijayadashami celebrations include processions to a river or ocean front that involve carrying clay statues of Durga,Lakshmi, Saraswati, Ganesha, and Kartikeya, accompanied by music and chants, after which the images are immersed in the water for dissolution and farewell. In other places, towering effigies of Ravana, symbolising evil, are burnt with fireworks, marking evil's destruction.
